To all whom it ymwy concern/.-

Be it known that I, SAMU L Know, of

Trenton, in thecounty of Mercer and State of New Jersey, have inventedcertain new ,and useful Improvements in Head-Rests, whereofthe-following is a specification, reference *be;

ing hadtothe accompanying drawings.

My invention relates to adjustable headrests whichmaybe employedwithparticu'lar advantage in connection with chairs designed be readilyadjustable without the employment ofthelon -handle'd bolts or nuts usualin head-rests this class, with the advam.

tage that there are no projections local to said head-rest to Iinterfere with ,the op erator.

As hereinafter described, my invention comprises a rack-bar arranged tobe longitudinally adjusted in a chair-back and having a cylindriformbracket arranged to support a head-rest block having a socket fitted tosaid bracket, said bracket and socket being provided with complementarymeans to secure them in any desired position of adjustment. Ashereinafter described, such means comprise a set-screw in the socketarranged to engage a peripheral groove in the bracket and complementaryserrations on the socket and on the bracket arranged forinterengagement.

My invention comprehends the various novel features of construction andarrangement herein set forth.

In the accom anying drawings, Figure I is a front View of a fragment ofa chair-back supporting a head-rest embodying my invention. Fig. II is acentral vertical sectional View of the parts shown in Fig. I and alsoshowing the up er portion of thechair-back cushion. Fi III is a centralvertical sectional view of a modified form of my invention.

In said figures, 1 is the head-rest-supporting bar arranged toreciprocate in parallel guides2, provided in the upper central portionof the chair-back frame 3. Said bar 1 is recessed to form a series ofrack-teeth 5, ar

Said. screw -l 6e xtends the circumferential groove 18 in .thebracket 13, so asto ermit .s ai d head-rest block'l5 to-be oscillatewithout lateralmove men w sa d. sc e i .slight m ctra ted In hef r otyiinventionshown n Fig- III the cylindriform bracket 20 :of ;the rack-,-bar21 i provided th:these rationsvw,a ra g to C perat with the omplmenta y so r ti n fi th cke 2 o t-the head-r s bl .25.

said block and replacing it with the serrations 22 and 23, engaged in'the desired position, in which it may be retained against accidentallateral displacement by the set-screw 26. This form of my invention isadvantageous in that it provides means to positively lock the head-restblock in any desired angular position without dependence upon the merefrictional engagement of the set-screw.

I do not desire to limit myself to the precise details of constructionand arrangement herein shown and described, as it is obvious thatvarious modifications may be made therein without departing from theessential features of my invention.

I claim- 1'. The combination with opposed parallel guides; of a barprovided with a rack arranged to reciprocate between said guides, andcarry a bracket with a cylindriform head provided with a peripheralgroove; a springpressed pawl pivoted. on said guides, arranged to retainsaid bar in adjusted osition; a head-rest block having a socket tted tosaid head; and, a set-screw carried by said block, arranged to engagethe groove on said head, substantially as set forth.

2. The combination with opposed parallel guides; of a supporting-bararranged to reciprocate between said guides and provided with a bracketwith a cylindriform head having serrations extending parallel with itsaxis; means arranged to retain said bar in adjusted he upper part of therack-bar 21 extends forwardly over the framegandhas its cylin= securedin any desired angular position rela tively to the bar 21 by laterallyremoving the position; a head-rest block provided with a v socket havingserrations fitted to the serrations on saidhead; and,vmeans arranged tonormally secure said head-rest block against lateral displacement withrespect to said 5 head, substantially as set forth.

3. In a head-rest, the combination with a bracket comprising acylindriform head having a peripheral groove; of a head-rest block avinga cylindriiorm socket fitted to said 10 head in removable relationtherewith; and a 2o tions fitted to the serrations on said head, in

removable relation therewith; and, a setscrew carried by said blockarranged to en- I gage said head and prevent the removal of said block,substantially as set forth.

5. The combination with opposed arallel guides; of a supporting-bararrange to reciprocate between said guides; a bracket carried by' saidbar, and having a cylindriform head with its axis extending transverselywith respect to said bar; means arranged to retain said bar in adjustedposition between said guides; a head-rest block having a cylindriformsocket fitted in removable relation on said head; and, means carried bysaid block arranged to engage said head and prevent the removal of saidblock, substantially as set forth.

6. The combination with opposed parallel guides; of a supporting-bararranged to reciprocate between said guides; a bracket carried by saidbar in rigid rel." tion therewith, and having a cylindriiorm head withits axis extending transversely with respect to said bar means arrangedto retain said bar in adjusted position between siid. guides; ahead-rest block having a cylindriform socket fitted in removablerelation on said head; and, means carried by said. block arranged toengage said head and prevent the removal of said block, substantially asset forth.

In witness whereof I have hereunto signed my name, at Trenton, in theState of New J ersey this 7th day of February, 1905.
